In Reply to: LOW COMPRESSION, PLS HELP!!! posted by Edgar on February 22, 2000 at 08:42:24:
11 bar = 159 psi
9 bar = 130 psi
7 bar = 101 psi
6 bar = 87 psi
: My authorized service says low compression in all cylinders in my 535i 1989. In four cylinders around 9, in one 7 and the last even 6 (I do not know what it means, should be compression ratio). They say, there should be around 11 in all cyl. What could be wrong?
